First of all, we can join more clubs, broaden our horizons and acquire skills while playing. Secondly, departments are also a good choice, which will generally improve our computer level, and we can also participate in some activities organized at ordinary times to relax.
Secondly, I think we can use network resources to watch some current events, understand some current political news and learn some retouching skills.
Finally, I think happiness is indispensable for a high-quality life. It's also a good choice to have a meal on the playground with three or five friends during study and leisure (in the case of school holidays), talk about the current situation on the playground, share each other's interesting things and plan the future. These will be the lubricants of happiness.
College life is the most relaxing time, so everyone must gain something and don't waste this time.
